1. DIFFERENCES IN THE USE OF BROADBAND: CATEGORY SIX CHANNELS PROVIDE AT LEAST 200MHZ OF COMBINED ATTENUATION-TO-CROSSTALK RATIO AND AN OVERALL BANDWIDTH OF 250 MHZ. CATEGORY SEVEN SYSTEMS CAN PROVIDE A COMBINED ATTENUATION-TO-CROSSTALK RATIO OF AT LEAST 500MHZ AND AN OVERALL BANDWIDTH OF 600 MHZ.

The performance improvement of Category 7 cabling is very significant, so that the transmission capacity and attenuation level provided by the copper cable media are close to that of fiber optic performance.

2. There are structural differences: Category 6 cabling systems can use both UTP and STP, while Category 7 systems are based only on shielded cables. In the seven types of network cables, each pair of wires has a shield, and the four pairs of wires together have a common large shield.

The non-RJ Type 7 cabling system uses double-shielded cables, which can meet the needs of those areas where shielded twisted pair systems are dominant.

3. There is a difference in the ability to connect hardware: the parameters of the seven types of systems require that all wire pairs provide at least 60DB of integrated proximal stringing when the connector is at 600MHZ. CATEGORY 5 SYSTEMS ONLY REQUIRE 43DB AT 100MHZ;

THE VALUE OF CLASS SIX AT 250MHZ IS 46DB. Usually use the Internet, and the maximum Internet speed is no more than 100 megabits. Ordinary Category 5 wire and super Category 5 wire can fully meet the needs.

Additional Information:

In the seven categories of cables, each pair of wires has a shield, and the four pairs of wires together have a common large shield. From a physical point of view, the additional shield layer allows the seven types of wire to have a large wire diameter. IN TERMS OF TRANSMISSION PERFORMANCE, THE CATHESIC CABLE CAN PROVIDE AT LEAST 500MHZ OF COMPREHENSIVE ATTENUATION TO CROSSTALK RATIO AND 600MHZ OVERALL BANDWIDTH, WHICH IS MORE THAN TWICE THAT OF THE CATHESIC LINE AND THE CATHETERIA LINE, AND THE TRANSMISSION RATE CAN REACH 10Gbps.

The biggest difference between the CAT7 network cable and the CAT7 network cable is that the bandwidth of the CAT7 network cable is 600MHZ, and the belt of the CAT7 network cable is 1000MHZ, which is the most fundamental difference in the performance of the two network cables

A new performance evaluation index has been determined for the six types of cables, using 23AWG single-core bare copper as the conductor, polyethylene polymer materials as the insulator, and flame retardant polymer materials as the outer skin materials, and the color is gray; Twisted pair cables meet the requirements of international specifications (ISO/IEC).
